1 Call For Papers
The Twenty-Seventh Conference on Principles and Practice of Constraint Programming (CP 2021) will take place in Montpellier, France from October 25 to 29, 2021. The conference site is easily reachable at CP2021. Montpellier is in the south of France, only 11km away from the Mediterranean and easily accessible by plane and rail. See details in the local information page.
The CP conference series concerns all aspects of computing with constraints, including: theory, algorithms, environments, languages, models, systems, and applications. It welcomes submissions that advance the state of the art for the underlying technologies as well as papers that explore the role of constraint programming within other disciplines such as operations research, machine learning, verification and planning.
The CP 2021 programme will include presentations of high-quality scientific papers and tutorials on both theory and applications. Invited talks will describe important topics relevant to the field. The CP programme also welcomes workshops for discussing in-progress work and provides support to students through its doctoral program, which includes a dedicated one day doctoral conference, mentorship by experienced researchers and more.
1.1 Tracks
The conference features a main Technical Track, and Thematic tracks:
- Application
- CP and Machine Learning
- CP and Operations Research
- Testing and Verification
Papers are submitted directly to one of the five tracks. Submissions that reach beyond classic constraint programming concepts are encouraged and welcomed alongside papers on constraint solving, NP-hard problem solving and optimization in general. Any underlying computational technique operating on a declarative constraint model are also welcome. Papers in specialized tracks will be reviewed by experts in that area.

1.3 Submissions Instructions
Paper submission is via EasyChair (CP 2021). Each submission should be directed to the suitable track.
1.3.1 Length and format
Noteworthy: CP21 is switching from Springer to LIPIcs for its proceedings. It is therefore crucial for authors to follows the guidelines provided below and not start from an old style file that is appropriate for Springer only.
The submissions should be submitted in the form of a PDF file following LIPIcs guidelines. The site linked above has examples and the necessary style files. Please read the directions attentively as specific LaTeX packages are prohibited or restricted.
To open the conference more widely (e.g., for OR persons), two types of submissions are expected this year:
- full papers: they can use up to 15 pages (references not included) but shorter submissions are also welcome. Submissions exceeding the page limits or improperly formatted will be rejected without review.
- short papers: they can use a maximum of 8 pages (reference excluded) and cover early results or results that can be adequately reported in just 8 pages. Short papers must nonetheless meet all the expected quality criteria of a full paper.
All papers should attract a wide audience and will be allocated time for presentation during the conference.
1.3.2 Anonymous Submission
To facilitate reviewing management, authors who intend to submit a paper to CP should submit a very short description of the contents and contribution of the final submission, with a maximum of 150 words, by May 14th, 2021.
The paper submission must be done before May 21th, 2021. All papers will go through a double blind reviewing process, meaning that authors and reviewers are anonymous to each other. For this reason, submitted full papers should not contain author names, affiliations, or links to identifying web sites. References should be cited in such a way as not to reveal the authorship of the paper.
1.3.3 Multiple Submission
A given paper must be submitted to exactly one track. When it looks necessary, the Program Chair may move a submission to another, more suitable track.
At the final submission deadline, any paper submission that appeared in, is accepted for, or is under review for another peer-reviewed conference or journal must be promptly withdrawn.
Submissions that have appeared at workshops or other meetings of lower status than a conference or only in highly shortened form (e.g., abstracts) can be submitted as papers.
1.3.4 Proceedings
Accepted papers (in all tracks) will appear in conference proceedings published by LIPIcs. The proceedings will be available at the time of the conference.
The program committee will select a set of outstanding papers that are invited to submit an extended version of their work to the Constraints journal in a fast-track review process. Authors if invited papers will be offered two options: (a) publication in the conference proceedings; (b) publication of an abstract in the conference proceedings, an online version of the paper submitted to the conference and the fast track. Note that Constraints is a Springer journal with its own formatting guidelines.
1.3.5 Pandemic considerations
As of late January 2021, the pandemic is still raging. Key dates shared earlier in this call may be adjusted (pushed back) as circumstances dictate. Please, check the conference site regularly to remain aware of any extension being added.
We do hope that the conference itself will be held in person. It is clear that the community values the availability of video recording of talks and CP21 will adhere to that practice no matter which modality is adopted for the October event. Authors of accepted papers will be expected to produce a recording of their talk ahead of time which will be shared via the ACP Youtube channel. Precise directions will be shared with the issuance of acceptance notifications.
1.3.6 Other Informations
Questions about the paper submission process may be addressed to the Program Chair Laurent Michel (ldm+cp21@engr.uconn.edu)
